Great work was done with the Pose and Facemesh Extensions
are there any plans to implement the hand gesture feature as well?
Mediapipe shows some more interesting functions we also could use here in AI environment 
Amazing work! Definitely there are great possibilities with AI. Thanks, Juan for the great sharing.
